Which is an adaptation that plants survive on land
a) diploid forms
b) photosynthesis
c)development of backbones
d) production of seeds

D

Explanation:

In water, an embryo can exist without desiccation hence remain viable until it is able to develop into another plant. On land, however, the embryo will be prone to desiccation and seeds are a plant’s adaption to survive life on land. The seeds have a pulp that provides the moist environment enclosing the embryo. In addition, seeds have a testa/seed coat that drastically lowers the rate of loss of water from the inside of the seed to the environment.
